It depends on the state and the school district that you apply to teach in. Maryland for instance will not evaluate your credentials until you obtain an indepedent national credential evaluation. I have included a few such institutions below as well as the Maryland statements from their website. Had to delete the phone numbers.
MSDE does not review specific documents from other countries. You must first obtain a course-by-course evaluation from a MSDE approved foreign evaluation agency.
To request a MSDE evaluation by mail, submit the following:
Qualifying scores on a Basic skills assessment (Praxis 1, SAT, GRE, or ACT); Additional tests, Praxis II or ACTFL may be required for full professional certification but are not needed for an initial evaluation. A photocopy of the score report is acceptable;
Original course-by-course evaluation in an unopened mailer from the approved foreign credentials evaluation agency;
